Installation Instructions
Pack Contents
To reduce on site installation time the Uponor Compact Control Pack V4 is available pre-assembled to the Uponor TM Manifold. The following is intended to give the installer the necessary information to install the V4 Compact Control Pack when bought in its preassembled form. If a Compact Control Pack (CCP) and Manifold are purchased separately then the installation instructions included with the CCP should be consulted prior to installation.
Main items:
4
• 1” Grundfos UPS 15-60 pump • Thermostatic head and pipe sensor • Preset immersion thermostat • 2-port thermostatic valve body, 1” MT x ¾” FT (BSP) • Lockshield valve, 1” MT x ¾” FT (BSP) • Thermometer • Manifold • 1” connection set with integral pump isolation valve • 1” connection set with immersion sensor pocket. • 2 x fill and drain points Note, The pack does not include fittings to go from the manifold on to the UFH pipe work. These need to be ordered separately. The fittings used will have to be suitable for the pipe size and pipe type used.
Introduction
• The Uponor Underfloor Heating (UFH) Compact Control Pack is a “designed for purpose” solution for controlling the flow and temperature of water in systems with up to 160m2 of active floor area and maximum 14kW heat load.
• The Control Pack comes pre-assembled on to the Uponor TM Manifold and is ready to be mounted on the wall straight from the box. It can also be supplied alone for coupling to LS manifolds and the larger size, 9 loops or more, TM manifolds.
• The thermostatic valve has a control head with a temperature adjustment range of 20 - 60 C. o
Operation
• During Heating Demand Periods
The Compact Control Pack is designed to mix the primary boiler flow water with the under floor heating return water. This is managed via a two port injection valve which is situated on the boiler flow which when open, allows the higher temperature boiler flow water to blend with the
Uponor Installation Guide
UFH return water in the return manifold. This maintains the required UFH flow temperature. An internal pipe sensor is fitted within the 90o elbow which operates the two port thermostatic injection valve. A secondary pump then circulates the water around the UFH loops. To ensure that the majority of the water is forced around the UFH pipe network, a lock shield is positioned on the return back to the boiler which is used for balancing the system.
• High Limit Protection
The Compact Control Pack also includes a failsafe device. A high limit thermostat which is fitted to ensure that water exceeding 60oC does not flow around the UFH system as per BS EN: 1264 since high temperature water may damage floor coverings. This thermostat will operate, in the unlikely event of a high water temperature condition, to switch off the electrical supply to the UFH pump therefore preventing overheat and possible damage to the floor.
